By referring to Figs. 1 to 9 of the. drawings, it 10 will be seen that Adesignates a casing which comprises a vertically extending grip portionIl) and a. right angularly extending nozzle carrying portion Il at theupper end of the grip portion lil and extending from one side thereof.The l5 casing A comprises a pair of hinged sections I2 and ,I3 which arehingedly connected, as at I4,

, the casing, as shown in Figure .4. The casing A is formed in twohinged sections to facilitate the placing or the operating mechanismwithin the casing and the removal thereof when occasion requires. 25

The nozzle carrying portion I I is provided with a cavity I6 in whichis.mounted a, spray nozzle I1 which has its discharge end I8 extending.through an aperture I9 formed in the outer end of the nozzle carryingportion Il, as shown in 30 Figure 4. The nozzle I'I communicates at itsrear end with the upper end of a pumping bulb 2li, which bulb extends inav vertical position and is snugly fitted within a pocket 2i formed inthe casing A, the sides of the casing being bulged, as 35 at 22, toconform to the contour of the bulb 20, as shown clearly in Figures 1, 2and 3.

A liquid reservoir 23 is supported in the lower end of the grip portionlil of the casing A, as shown in Figure 4, the reservoir 23 comprising a4o tank-like body having notches 24 along its top and llottom ends forreceiving the spring clips 25 of the supporting bracket 26, whichbracket 26 is xed to one wall of the section I2 of the casing A. Thisbracketl 26 is provided witha pair of 45 vertically extending spacedears 21 also engaging the side of the reservoir or tank 23 to facilitatethe holding of the tank or reservoir in position.

. By means of this structure, the tank or reservoir 23 may be easilyremoved and replaced in position 50 when desired. f y

The tank or reservoir 23 is provided with the upstanding threaded neck28 within which is tted and securely positioned a collar 29 havinglupstandiug lugs 30 which nt into suitable sockets 55 key or button 34carried by the casing A, this key or button 34 preferably tting within acountersunk socket 35. The valve casing 3| is provided with a port 36which communicates with a pipe 31 leading to the lower end of the pumpbulb 20 and is also provided with a port 38 communicating with a pipe 39which is connected at its opposite end to the spray nozzle I1 near theouter end of the discharge nozzle, as shown in Figure 4. The valve 33 isalso provided with ports 40 and 4| which are adapted to communicate withthe` ports 36 and 38 respectively, as will be obvious. The outer end ofthe valve 33 is provided with a socket 42 which receives the inner endof the key or button 34 to allow the valve 30 to be properly operated tocut on the iiow of fluid from the tank or reservoir 23 or to permit theow through the valve, as will be obvious.

It will be seen by carefully considering Figure 6 that the pipe 39 isoffset with respect to the vertical center of the bulb in order topermit the inner end 43 of the operating trigger 44 to engage the bulbfor the purpose of compressing the bulb 20 without interfering with orengaging the pipe 39. This structure is shown clearly in Figure 6. Thetrigger 44 is slidably mounted within the casing A in a position toextend at right angles to the bulb 20 and is slidably mounted within thecut-out ringer-receiving portion 45 located directly below the nozzlel1. Ball-bearings engage the trigger 44, as shown in Figure 4, tofacilitate the sliding of the trigger. 'I'he expansion of the bulb 20after the trigger is released will cause the trigger to return to itsnormal position without the necessity of employing a spring.

The particular form shown in Figure 1 is constructed in such almanner asto facilitate the handling and holding of the sprayer in the hand of theoperator since the vertical grip portion may be gripped in the handbetween the iingers and thumb and the forefinger may engage the trigger44, the casing A being of a pistol-like structure. The construction ofthe device also is quite compact and may be placed easily within thepurse or hand-bag of the user,

In the form shown in Figures 10 to 12 inclusive, a casing B isillustrated comprising a grip portion 50, and a nozzle carrying portionwhich nozzle carrying portion extends at right angles to the gripportion and from one en d thereof. The casing B is split longitudinallyto provide longitudinally extending tted sections 52 and 63 which arehingedly connected at their upper ends, as at 54, whereby the sectionsmay be swung apart for the purpose of obtaining access to the interiorof the casing B. A suitable latching device 55 is carried at the lowerends of the sections 52 and 53 to hold the sections in closed relation.I

A finger guard 56 is formed directly under the nozzle carrying portion5| within whichguard is pivotally mounted a trigger 51, as at 58, whichtrigger is of a bell crank structure having a pivoted shoe 59 at itsinner end for engaging the pump bulb 60 which pump bulb extendstransversely across the top of the grip portion 50, and in line with thespray nozzle 6|. The bulb 60 is connected at its rear end to thereservoir 62 which is mounted in the lowex end of the grip portion 50 bymeans of a pipe 83 and a pipe 64 extends from the reservoir 62 to thenozzle 6| at a point near its discharge end. A shut-off valve 65 iscarried by the upper end of the reservoir 62 and is provided with acontrol button 66 tting ush with the outer face of the casing B topermit the reservoir to be cut-ofi when the device is not in use andprevent leakage.

In the form shown in Figures to 12 it will be seen that the bulb 60 liesupon the shoe 59,

and by pulling the trigger 51 the bulb 60 will be compressed upwardlyagainst the top 61 of the casing B, the resiliency of the bulb providingsufficient spring action to return the trigger 51 to normal whenreleased. The bulb 60, as well as the bulb 20, is of the conventionalpump type having an air inlet valve 68 at its rear end for supplying airto the bulb whereby air may be forced down through the pipe 63 into 'thereservoir 62 driving the fluid up through the pipe 64 into the spraynozzle 6| where it is engaged by an air column from the bulb 60 in orderto produce a spray. I do not desire to limit my invention to anyparticular type of spray nozzle, although I have illustrated and willdescribe in the following a special type nozzle which has been foundsuitable.

bulb 82 and an expansible'lever mechanism 83 of the lazy tong structure,carryingl a slotted shoe 84 which engages the bulb 82. This expansiblelever mechanism 83 carries an upwardly inclined arm 85 which in turnengages a pivoted link 86 which link is connected to a trigger slide 81,the trigger slide being slidably mounted withinthe guide 88 locatedabove and intermediate the compartments 19 and 80. A spray nozzle 89 iscarried by the upper end of the casing D and an air tube 90 forms acommunication between the nozzle 89 and the bulb 82. A pipe 9|communicates with the bulb 82 and the reservoir 80 and a pipe 92communicates with the reservoir 8 and the nozzle 89 near its dischargeend, the-parts operating in the manner similar to that previouslydescribed. 'Ihe reservoir 8| is provided with a suitable cut-off valve8| similar to the valves 33 shown in Figure 8, and 65 as indicated inFigure 12.

In Figure 14, I have shown a still further modified type ofthe inventionillustrating a casing E carrying a bulb 93 at its upper end extendingtransversely across the same and carrying a forwardly extending spraynozzle 94 which projects through the nozzle housing 95. A reservoir 96is located below the bulb and communicates therewith by means of thepipe 91, the reservoir also communicating with the nozzle 94 by means ofa pipe 98. A trigger slide 99 is slidably mounted within the triggerguard |00, and this trigger 99 is connected to the expansible lever orvlazy tong structure |0| which is anchored, as at |02, at one end andcarries a'pusher shoe |03, the pusher shoe engaging the under face ofthe bulb 93 for compressing the bulb as the trigger 99. is reciprocated.

In Figures 15 and 16, I have shown a special type or form of the bulbindicated by the numeral |04 which is provided with longitudinally exofthe grip portion and under the houle carrying tending tapered ribs loslthroughout the length thereof to prevent the complete collapsing of thebulb, and to also reinforce the contacting face which is engaged by thepusher shoe.

Although I do not desire to unnecessarily limit myself to any particulartype of nozzle, I have found'that the type of nozzle as illustrated inFigures 17 and 18 may be utilized to good advantage wherein a casing |29is provided having a sprayer neck |30 therein, the sprayer neck hav-.ing an air pressure port |3| extending longitudinally thereof, and theneck being provided Iwith flattened faces |32 upon its upper and lowerfaces, whereby the air pressure passing through the port or channel |3|cause the liquid to pass through the channels provided by ,the attenedfaces |32 thereby atomizing the liquid as it is discharged from theapertured cap |33.

In the type shown in Figures 19 and 20, the

-nozzle tube |34 is provided having a longitudinal air pressure port |35formed in the sprayer neck |36, the sprayer neck -being provided with aplurality of longitudinally extending substantially V-shaped notches |31along its side face to allow fuel to be drawn up through the tube |38and be atomized out through the apertured cap |39 in the conventionalmanner.

From the foregoing description-it should be understood that although thepresent device is especially adapted for use as a perfume sprayer, thesame may be utilized for spraying any liquid without vdeparting from'thespirit of the invention so long as the structural features fall withinthe scope of the appended claims.
